Embodiment Construction

[0043]In SAE, there are several possible solutions for deactivating all the bearers corresponding to an APN of the user by sending a delete bearer message. One is to send a specific Deactivation APN Request message to the MME through the UE, and the other is to send a Deactivation APN Request message to the MME through the UE. The Detach Request message is implemented, but for these two methods, the MME sends the Delete Bearer Request message to the S-GW, and then the S-GW sends the Delete Bearer Request message to the PDN GW, and the two messages will also carry a teardown indication Indicates that all bearers corresponding to this APN will be deleted.

[0044] In the embodiment of the present invention, the deactivation of the APN and the detach process are distinguished between the MME and the S-GW, so that the UE sends a Detach Request message to the MME (or the MME to the S-GW) to notify the MME (or S-GW) to achieve detachment Operation, delete all the bearers correspondi...

Abstract

The invention discloses a method for deleting bearing. The method comprises the following steps: first equipment receives a request message sent by second equipment, and the request message carries indication information differentiating de-adhesion and de-excitation; and the first equipment executes the de-adhesion or de-excitation operation according to the indication information. The invention discloses a system and equipment for deleting bearing. In the embodiment of the invention, a Detach flow and a de-excitation APN flow are differentiated by extending indication parameters, and simultaneously the Detach flow or the de-excitation flow can be completed by MME and S-GW being interacted one time only.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, system and equipment for deleting a bearer. Background technique [0002] UMTS (Universal Mobile Telecommunication System, Global Mobile Communication System) is a third-generation mobile communication system that adopts WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) air interface technology, and the UMTS system is usually called a WCDMA communication system. The UMTS system includes RAN (Radio Access Network, radio access network) and CN (Core Network, core network). Among them, RAN is used to handle all wireless-related functions, while CN handles all voice calls and data connections in the UMTS system, and realizes switching and routing functions with external networks. [0003] At present, in the LTE (Long Term Evolved, long-term evolution network) / SAE (System Architecture Evolved, system architecture evolution...
